Finished and Functional

I have a glass water bottle that I use at work. It is my small effort to save the planet and stay hydrated. It originally came with a rubbery cover that unfortunately tended to trap debris and general nastiness. This did not seem healthy or sanitary, so I took it off and knit a water bottle cozie for it instead.
